Starting Your Business the Right Way
This start a business guide walks you through every critical step for launching your company in Illinois. Starting a business is one of the most consequential financial and legal decisions you will make. The choices you make in the first weeks — entity structure, ownership allocation, contracts, intellectual property protection, and compliance — create the foundation that everything else builds on. Getting these decisions right from the beginning is far cheaper than restructuring later.
At Howard East, we help entrepreneurs across Illinois, Missouri, New York, and Wisconsin launch businesses with the legal infrastructure they need to grow, raise capital, and operate without unnecessary risk.
Step 1: Choose Your Business Structure
The entity you choose — LLC, corporation, partnership, or sole proprietorship — affects your personal liability, tax obligations, ability to raise capital, and administrative requirements. Most small businesses benefit from an LLC structure for its combination of liability protection and tax flexibility. Companies planning to raise venture capital or issue stock options typically form C-corporations.
We help you evaluate the options based on your specific circumstances, including your industry, the number of owners, your funding plans, and your long-term objectives.
Step 2: File Formation Documents
Once you have chosen your structure, you need to file articles of incorporation (for corporations) or articles of organization (for LLCs) with the state. You will also need to obtain an employer identification number (EIN) from the IRS, register for state taxes, and comply with any local business licensing requirements.
Step 3: Draft Governing Documents
Your formation filings create the entity, but your governing documents — operating agreements for LLCs, bylaws and shareholder agreements for corporations — define how it operates. These documents address ownership percentages, voting rights, management authority, distribution policies, transfer restrictions, and exit mechanisms.
If you have co-founders, this step is critical. The governing documents should address what happens if a founder leaves, wants to sell their interest, becomes disabled, or simply disagrees with the direction of the business.
Step 4: Protect Your Intellectual Property
Register your business name and logo as trademarks. Ensure that any intellectual property created by founders, employees, or contractors is properly assigned to the company through written agreements. Implement confidentiality agreements for anyone with access to proprietary information.
Step 5: Set Up Contracts and Compliance
Before you start selling, make sure you have the contracts you need: customer agreements or terms of service, vendor and supplier contracts, employment agreements and offer letters, independent contractor agreements, and privacy policies if you collect customer data.
Compliance requirements vary by industry and jurisdiction. Our attorneys identify the regulatory obligations that apply to your business and help you build compliance into your operations from day one.
